Four reasons to refactor your applications

This position paper explains why refactoring applications is a critical step in modern application modernization, especially for organizations aiming to deliver AI-powered, high-performance experiences to distributed users. Refactoring updates application architecture using modern technologies—such as serverless, microservices, and AI—without changing core functionality, helping organizations reduce technical debt, improve agility, and future-proof their platforms.

• Reduce costs: Refactoring lowers technical debt, cuts infrastructure and maintenance costs, and enables efficient serverless and edge-based AI execution.
• Improve performance: Distributed, composable, serverless, and observable architectures deliver faster, scalable, and globally optimized user experiences.
• Increase developer velocity: Modern platforms, APIs, and infrastructure-as-code accelerate development, deployment, and AI integration.

In addition, refactoring strengthens security and compliance by removing legacy risks and applying unified security controls across environments. Cloudflare’s connectivity cloud provides a unified, programmable platform that enables organizations to refactor applications faster, improve performance and scalability, enhance security, and support AI-driven innovation—helping teams modernize with less risk and faster time-to-value.
